【摘要】：引入集中控制理念的软件定义网络(SDN)技术为网络的智能化提供了新的思路,但也同时在业务的端到端传输时延中引入了控制时延。详细阐述了SDN架构下,硬件资源和流表下发模式对控制时延的影响,在仿真环境和实际测试中,开展了两种流表下发模式下端到端时延对比和应用系统控制时延对比。从数据分析中可以得出Reactive模式拥有较高的自动化程度与灵活性,但会引入高控制时延,Proactive模式的控制时延很低,但需要人工干预和预配置。基于对比结论,结合现网业务承载方式,建议电力通信网中涉及路由的承载方式可采用SDN技术进行优化,通过预配置业务路径,以Proactive模式保障实时性,同时支持Reactive模式,应对复杂网络的灵活性需求。
[Abstract]:The software defined network (SDN) technology based on the concept of centralized control provides a new way of thinking for the intelligence of the network, but also introduces the control delay into the end-to-end transmission delay of the service. In this paper, the influence of hardware resources and stream table down-sending mode on control delay in SDN architecture is discussed in detail. In the simulation environment and the actual test, the comparison between the end to end delay and the control delay of application system is carried out. From the data analysis, it can be concluded that Reactive mode has high automation and flexibility, but the control delay with high control delay and active mode is very low, but it needs manual intervention and pre-configuration. Based on the comparison conclusion, it is suggested that the route bearing mode in power communication network can be optimized by SDN technology, and the real-time performance can be guaranteed by Proactive mode, and the Reactive mode can be supported by pre-configured service path. Meet the flexibility requirements of complex networks.
